    8. USAGE EXAMPLE 8.4 Contents Check of COM-JG Initial Setting The contents of the COM-JG initial settings vary depending on the module configuration, number of communication items, and communication content. For this reason, before using the PLC configuration tool (Programming Software STEP7) to configure each setting, the module configuration, number of communication items, and communication content required in the COM-JG initial settings must be checked.
  • Page 70 Controller address Overview To allow the PLC and COM-JG to communicate, the COM-JG must be made to recognize the address of each controller (the module addresses of the SRZ). Controller addresses can be obtained automatically by COM-JG DIP switch switching, or controller addresses can be set using the PLC configuration tool.

After you have completed the COM-JG initial settings, be sure to return DIP switch No. 7 to OFF (controller communication enabled).
  • Page 77 (P. 102) item setting In the COM-JG initial settings, the number of data that is read or written varies by setting item and thus the procedure must be repeated for each setting item. However, when the number of data read or written is the same, such as for “Static data read range” and “Static data write range”, the settings can be configured together.
